I thought of arpwatch but dismissed it for two reasons:

  1. It does not come "standard" everywhere which in my mind is a minor reason to not include it.
  2. Because as you pointed out it is a daemon and not a CLI utility (IIRC) it isn't much use to a Perl programmer.

There are other utilities as well such as tcpdump and snoop but I think they aren't what the OP had in mind either.

If what you are after is to take an ETHERNET address and convert it to an IP address "right now" then none of the utilites such as snoop, arpwatch or tcpdump are going to be of much use.
